More Details:	[Objective] This study aimed to investigate the green watersheds development in the Yangtze River Economic Belt (YREB) from the perspective of human-water relationships, which is key to the coordinated development of the water ecological environment and economy. [Methods] This study constructed a comprehensive evaluation system covering water resources, water environment, water ecology, and water economy. It used entropy weight TOPSIS, Dagum Gini coefficient decomposition, and kernel density analysis to analyze the green watershed development level, spatial differences, and changes of 108 cities in the YREB in 2010, 2015, and 2020. Additionally, it identified shortcoming areas in green watershed development based on the main functional zones. [Results] (1) From 2010 to 2020, the overall green watershed development improved. The distribution pattern was higher in the downstream, moderate in the midstream, and lower in the upstream, with levels higher near the river and lower farther away. (2) From 2010 to 2020, the overall spatial disparities in green watershed development across the YREB gradually narrowed. Specifically, disparities in the middle and lower reaches decreased significantly, reflecting a more balanced development; in contrast, disparities in the upper reaches initially declined but later showed a slight increase. (3) From 2010 to 2020, green watershed development levels increased in the order of optimized development zones > restricted development zones > key development zones, reflecting a gradient difference in human-water relationship regulation across regions. The water economy index in the optimized development zones was highest, while restricted development zones excelled in water resources, environment, and ecology. (4) The distribution of shortcoming areas in 2020 revealed significant differences in core contradictions in human-water relationship coordination: optimized development zones (except Shanghai) generally faced water economy or ecological problems; key development zones were concentrated in core cities of the Chengdu-Chongqing and Wuhan metropolitan areas, with significant water economy shortcomings; restricted development zones, most in inter-provincial border cities, facing water resource and economy issues. [Conclusion] Regional human-water relationship coordination is a key driving force for promoting green watershed development. The study recommends enhancing cross-regional coordination, promoting the coordinated development of water resources, environment, ecology, and economy, and formulating differentiated green watershed strategies based on functional zones to sustain human-water relationship change in the YREB.
